Cygnus Series – Carrying on a Legacy - 2012-present
As promised to Ardent customers, the large displacement 4-cylinder replacement to the Orion series arrived. The 2.2 Cygnus versions were bored and stroked (evenly, retaining its squarebore design) to 2.4L, while the 1.4L was similarly debored and destroked to 1.2L, gaining a naturally aspirated twin in the process. All motors in the series received direct injection technology and forged crankshafts.
Though this raised the costs of the motors significantly, Ardent had made clear that their focus for the future was on reliability and economy.
CT4-G, the new 2.4L turbo version of the Cygnus slated for the replacement to the Orion-powered Marathon. Though not nearly the firebreather than its 6-cylinder ancestor was in the end, it hit the magic 200 horsepower mark, and the coupe it powered was much lighter. Within the company, there was a metaphoric torch for small performance engines since the Sixties. Though unofficially passed a decade earlier, this was now, to the public, officially raised by the Cygnus series…
